With the development of networks and embedded technologies,more and more importance has been attached to how to combine embedded techniques with traditional gereral-purpose communication protocols.Different Embedded Systems have different criterias such as response time and real time for the communication protocols,so cutting out conventional TCP/IP suitable in the embedded system has become the key problem when designing an embedded communication protocol stack.Firstly,this thesis breifly introduces the embedded system,embedded communication protocol’s characteristic and background of this thesis-embedded firewall.Next,combined with the background,this thesis amply discusses the designation of the whole embedded communicaion protocol stacks including the memmory buffer,input disposal and etc.Secondly,this thesis puts forward the implementation of the embedded communication based on S3C44B0X chip.The detailed work is as follows:Programming the RTL8019AS driver based on SC44B0X chip, transplantation ofμC/OS-II and the implementation of each modules of embedded communication protocols based on SC44B0X.Lastly,each communication protocol stack module has been tested respectively.
